MR Observations of Posttraumatic Osteolysis of the Distal Clavicle After Traumatic Separation of the Acromioclavicular Joint

Abstract

The MR features of posttraumatic osteolysis are characteristic of this process. We advocate the use of MRI in patients with chronic AC joint pain who have had a prior AC joint dislocation, particularly if follow-up radiographs are nonspecific, equivocal, or do not indicate the presence of secondary osteoarthritis.

Comparison of surgical and conservative treatment of Rockwood type-III acromioclavicular dislocation

“…Osteolysis of the lateral clavicle may be related to disorders in the microenvironment of the distal clavicle, but the specific mechanism is not known. [ 21 ]…”

Effect of Wheelchair Stroke Pattern on Upper Extremity Muscle Fatigue

“…Prevalence of shoulder pain is highest among manual wheelchair users with tetraplegia and paraplegia [2], who use their upper limbs repeatedly each day for wheelchair propulsion and transfers. Studies using ultrasonography [19], physical examination [20,21], and magnetic resonance imaging [22] have shown that the shoulder pain in manual wheelchair users is attributed to various pathologic changes, including rotator cuff tears [7,23], degenerative changes [20,24], impingement [25], and osteolysis [22,26]. Shoulder abnormalities have been linked to propulsion biomechanics [27,28] and muscle imbalances [13,29].…”

Successful treatment of the post-traumatic osteolysis of distal clavicle with alendronate

“…20 However, osteolysis has also been repeatedly described in patients with no radiological pathologies after the injury. Although usually self-limiting within 18 months, post-traumatic osteolysis may lead to irreversible vanishing of the distal 0.5-3 cm of the clavicle.…”
